摘要： Inner circumferential surfaces of a rotor holder and a turntable are in contact with an outer circumferential surface of a shaft. This stabilizes coaxiality of both the rotor holder and the turntable with respect to the shaft. An upper cover portion of the rotor holder includes fixing holes. The turntable includes fixing projections arranged to extend through the fixing holes to be in contact with a lower surface of the upper cover portion. A base end portion of each fixing projection is arranged at a level higher than that of an upper end portion of a corresponding one of the fixing holes. Therefore, even if dimensional errors of the rotor holder and the turntable cause a radial displacement between any fixing projection and a corresponding one of the fixing holes, the rotor holder and the turntable can be fixed to each other while maintaining coaxiality therebetween.

摘要： In a chucking device, a rolling guide portion is arranged below an upper cover portion of a rotor holder and radially inwards of a cylinder portion of the rotor holder. This helps restrain the noises generated by the rolling movement of balls from propagating to the outside. Moreover, the turntable and the rolling guide portion are formed of a single resin member extending continuously through a through-hole defined in the rotor holder.

摘要： A chucking device for removably holding a disk with a central opening, includes a shaft coaxially arranged with a specified center axis; a turntable fixed to the shaft, the turntable having a disk support surface for supporting the disk; and a resin-made cone arranged axially above the turntable, the cone including a shaft-fixed portion fixed to the shaft, a disk holding portion having an annular disk holding surface inclined radially outwardly and axially downwardly, and an arm portion for radially interconnecting the shaft-fixed portion and the disk holding portion. Herein, the arm portion includes a support portion extending radially outwardly from the shaft-fixed portion and an elastically deformable portion joined to the support portion for being elastically deformed to axially downwardly move the disk holding portion as the disk comes into contact with the disk holding portion.

摘要： A magnet disposed on the top face of an extended part of a bearing holding member has a semicircle shape as the maximum shaper and is disposed in the same direction as the movement direction of a disk dray in the circumferential direction. By the pulling force in the axial direction between the magnet and a rotor holder, the shaft tilts at an angle different from the gravity direction or a direction opposite to the gravity direction.

摘要： A chucking device includes a turntable fixed to a shaft having a central axis and a cone arranged axially above the turntable. An annular yoke is arranged above a sliding portion of the cone and fixed to the shaft, and a clamp magnet is fixed to the yoke through an adhesive agent. The yoke includes an upper surface having an annular recess defined in a concentric relationship with the central axis, the adhesive agent being applied on a region of the upper surface existing radially inwards of the recess. The recess includes a radial outer wall parallel to the central axis and a radial inner wall inclined radially inwards and axially upwards. The angle between the radial outer wall and a lower surface of the clamp magnet is greater than the angle between the radial inner wall and the lower surface of the clamp magnet.
